New records set for the concentration of harmful gases in the atmosphere. UN: “On the climate trajectory leading to catastrophe”

The levels in the atmosphere of three main greenhouse gases, namely (carbon dioxide, methane and nitrogen dioxide) hit new records in 2021, according to a new report from the World Meteorological Organization. The concentration of Co2 reached 415.7 parts per million (ppm), methane at 1908 parts per billion (ppb) and 334.5 parts nitrogen dioxide per billion. The values ​​are respectively 149%, 262% and 124% of pre-industrial levels. The increase in Co2 from 2020 to 2021 was higher than the average annual increase of the last 10 years. In 2021 there was the largest annual increase the methane concentration of the last 40 years.

According to theUnited Nations Organization, government plans to reduce harmful gas emissions are not enough to avoid a “catastrophic” evolution of global warming. The trajectory is that of an increase in average temperature between 2.1 and 2.9 degrees centigrade by the end of the century, almost double the increase of 1.5 degrees agreed with the 2015 Paris agreements and considered a tolerable threshold. In a bleak scenario, one piece of good news: emissions are expected to stop rising after 2030. The United Nations Executive Secretary for Climate Change said today Simon Stiell.

An alarm came today also from the European Environment Agency (Aea) according to which for achieve the goals set for 2030 in the fight against climate change efforts owe more than double up. We read in the latest report on trends and projections for Europe. In 2021 EU emissions have started to rise again, it is noted in the document, but they remained at a level that is still lower than in 2019. While in 2020 the EU and the Member States reached the targets set for cutting emissions, renewables and energy efficiency. The next November 6 will open in Egypt there Cop27, the United Nations International Climate Conference. Many observers fear a flop with a retreat from the vague commitments made at the previous London conference. The energy emergency triggered by the war in Ukraine has led many countries to resume the use of highly polluting sources such as coal.
